Many changes have taken place in agriculture over the last 100 years. While most of the emphasis in commercial agriculture has been on maximizing yield, with truly remarkable results, this shift in focus also led to an incredible loss of bio-diversity and significant cultural losses in some communities around the world.

It’s estimated that in the last century 94 percent of global seed varieties have been lost. The new documentary Seed: The Untold Story, gives some insight into how this happened and shares the stories of people working hard to preserve the seeds that are left.

On this edition of Talk of Iowa, host Charity Nebbe talks with the co-producer and director of Seed, Jon Betz, as well as Tim Johnson of the Seed Savers Exchange in Decorah.

Seed will debut on Iowa Public Television on April 19th at 6 p.m.

Hybrid seed corn and nitrogen fertilizer transformed farming in the 20th century, but they are also closely tied to some of today’s major agricultural challenges. That has prompted some members of two families that played pivotal roles in developing farm innovations to work on putting a lighter, 21st century stamp on the landscape.

In Carlisle, Iowa, Rob Fleming still uses the 1947 Ford 2n tractor he drove on the family farm as a teenager. Back then, his family’s fields were lined with neat rows of corn. Not anymore.
